Spots Global Cancer Trial Database for Cetuximab, Cisplatin, Fluorouracil, and Radiation Therapy in Treating Patients With Anal Cancer

Study Description

Brief Summary: RATIONALE: Monoclonal antibodies, such as cetuximab, can block tumor growth in different ways. Some find tumor cells and kill them or carry tumor-killing substances to them. Others interfere with the ability of tumor cells to grow and spread. Drugs used in chemotherapy, such as cisplatin and fluorouracil, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Radiation therapy uses high-energy x-rays to kill tumor cells. Cetuximab may help cisplatin and fluorouracil work better by making tumor cells more sensitive to the drugs. It may also make tumor cells more sensitive to radiation therapy. Giving cetuximab together with chemotherapy and radiation therapy may kill more tumor cells. PURPOSE: This phase II trial is studying how well giving cetuximab together with cisplatin, fluorouracil, and radiation therapy works in treating immunocompetent patients with stage I (closed to accrual as of 11/3/2008), stage II, (some stage II closed to accrual as of 11/3/2008) or stage III anal cancer.

Detailed Description: OBJECTIVES: Primary Objective: * Determine whether the addition of cetuximab to combined modality therapy (CMT) comprising cisplatin, fluorouracil, and radiotherapy reduces the local failure rate by ≥ 50% at 3 years (compared with historical data) in immunocompetent patients with stage I-III invasive anal carcinoma. Secondary Objectives: * Determine objective response rate (complete and partial), progression-free survival, colostomy-free survival, and overall survival. * Determine the overall toxicity of concurrent cisplatin, fluorouracil, and radiation therapy combined with cetuximab. Exploratory Objectives: * Evaluate the effect of cetuximab and CMT on anogenital herpes papilloma virus (HPV) infection and anal cytology. * Evaluate whether moderate to strong expression of epidermal growth factor receptor, Phosphatidylinositol-4,5-bisphosphate 3-kinase (PI3K), and P-Akt (as determined by immunohistochemistry) is associated with an increased risk of local failure. OUTLINE: This is a multicenter study with two sequential arms. Arm I was closed to accrual as of 11/3/2008, and arm II opened to accrual on 8/18/2009. Patients are assigned to 1 of the 2 treatment arms. * Arm I (closed to accrual as of 11/3/2008): Patients receive cisplatin intravenously (IV) over 60 minutes on days 1, 29, 57, and 85 and fluorouracil IV continuously over 96 hours on days 1-4, 29-32, 57-60, and 85-88. Patients also receive cetuximab IV over 120 minutes on day 50 and then IV over 60 minutes on days 57, 64, 71, 78, 85, 92, and 99 and undergo radiotherapy once daily 5 days a week for 5 weeks, beginning on day 57. * Arm II (open to accrual on 8/18/2009): Patients receive cetuximab IV over 120 minutes on day 1 and then IV over 60 minutes on days 8, 15, 22, 29, 36, 43, and 50. Patients also receive cisplatin IV over 60 minutes on days 8 and 36, fluorouracil IV continuously over 96 hours on days 8-11 and 36-39, and undergo radiotherapy once daily 5 days a week for 5 weeks beginning on day 8. After completion of study treatment, patients are followed periodically for up to 10 years. PROJECTED ACCRUAL: A total of 62 patients will be accrued for this study.
